Application filed March 11, 1912. Serial No. 682,836.

To all whom it may concern:

Be it known that we, SAMUEL JAMES FISHER, a. British subject, and residing at No. 287 Chestnut street, in the city of Asheville, in the coimty of Buncombe, and in the State of North Carolina, and CHARLES EARL Jomvsox J owns, a citizen of the United States of America, residin at No. 37'? Montford avenue, in the sai city of Asheville, county of Buncombe, and State of North Carolina, have invented a new and useful Apparatus for Disinfecting Books,'of which the following is a specification. Our invention relates to improvements in fumigating machines and is adapted especially for fumigating books by discharging germicidal gas within a chamber against the edges and between the leaves and interstices of the books to be disinfected, said books being secured in a suitable manner .upon shelves adjustably mounted upon a revoluble standard within said chamber relative to nozzles and fans therein disposed in such manner as to blow a germicidal gas upon, into and between the leaves and interstices of the books.

The case housing the apparatus is preferably tubular and is divided into compartments separated from one another by division plates and is provided with valves and valve-controlled intakes and vents and also doors, the fumigating chamber being provided with air-tight doors and is adapted to receive the books to be disinfected and retain compressed gas and air without leakage.

Operative power may be supplied from any suitable source of energv.

A sterilizing tank is provided for the gases discharged after service, the gas being discharged beneath the surface of the fluid in the tank and forced to rise to the surface in small globules. There may be a plurality of such tanks though only one is illustrated and these tanks may be positioned without the case and the fluid heated convenient manner. These tanks in any constructed of any may. be lined with or suitable material.

(iases discharged in the fumigating chamber may be exhausted into the supply tank and supply pipes and redischarged therein. and thus continuously returned into the fumigating chamber.

Suitable mechanism actuates the bookstand and any style of nozzle or gas tip may be employed. Likewise any style of rotary fan, blower, cage and shield may be utilized without departing from the spirit of this invention.

Our invention will more fully appear as the description proceeds and will be distinctly pointed out in the claims but it is evident that we do not restrict it to the precise form and style illustrated in the drawlugs but it-may be embodied in other structures which substantially correspond with the claims inasmuch as the central feature of the invention is to present the books to be disinfected upon a revoluble supporting member in front of a plurality of nozzles or tips or vents discharging thereinto gas or air under pressure and revolving fans whose function is to blow the released gas or air into and between the leaves of the apparatus in the sterilizing tank The apparatus is inclosed in a vertical, cylindrical case 29 which is secured to and rests upon a vertical drum-base 10. These are preferably of metal construction.

10 is the division plate which separates the drum-base 10 from the cylindrical case '29 and 10 is the division plate between the air tank at the bottom of the drti"-b*a"'seand the operating chamber in said drum base arranged immediately above it. 1095 the door to said operating chamber in are drum-base.

A is the air-tank adapted to chamber compressed air and it receives its supply by a service pipe A with cut-off valve A. A plurality of pipes tap the air-tank A. All of these pipes are fitted with suitable valves to shut oif and control flow of air. The pipe 22, fitted with a check valve 2'2 connects the air-tank A with a portable gas-tank 13 Pressure gages are fitted to said pipe 2'2 fore and aft said check valve.

22" are the air pipes leading from the airtank A to the fumigating chamber 3 These air pipes are adapted to discharge air'or gas as desired and for that purpose they are connected to the cocks 20 at either end of the portable tank B by branch pipes B. Intermediate the air tank A and the T joints connecting the pipes 22 with the gas tank B are'the valves 22 These valves are so arranged that either air or gas or both may be discharged through the pipes 22 as desired. The pipes 22* pass through the division plates 10 and 10 and proceed vertically into the fumigating chamber 31 above=the drum-base 10 where they are pro vided- 'with horizontal extensions The pipes 23 converge toward the standard 26. They connect with the pipes 22 by T joints or elbows. l

A plurality of air-spray nozzles 30 are laterally disposed upon the pipes 22" and are dependent from the pipes 23 within the fumigating chamber 81. These nozzles are adjustable and may be regulated by a small valve or cock in said nozzles. They are so disposed upon the pipes as to vent their contents upon and between the edges and leaves of the books secured to the book holders or book racks or supports 45 by the clamps or book-clips 47 which are vertically adjustable upon the upright members of said book racks.

The books to be disinfected are preferably positioned upon the book shelves 24 with their edges adjacent the rim of the shelf. Thus they are disposed in an upright position' with their backs adjacent the standard and their board edges secured by the clips 47 and their boards clamped between the jaws of the clips.

The pipes 23 are horizontal extensions of the pipes 22 and they converge toward the standard 26. They are closed at their ends and are fitted with lateral, spaced curvilinear extension pipes 93 as shown in Fig. 4c. The pipes 23 are supported by the pipes 23 and are concentric. The pipes 23 are fitted with dependent vents or nozzles and they receive their supply of gas at their termini from the pipes 23 with which they unite.

23* are the valves or cocks which shut off the supply of gas or air from the pipes 23 and 23. They are fitted to the T joints 23 or the pipes 23.

The book-shelves 9% are disk-plates preferably perforated and constructed of metal. These shelves. however. while disk shaped may be scgmentmland assembled upon their supports in any suitable or convenient manher and tllr-Y are fitted with a central aperture'or core corresponding with the peripherv oi the standard. These shelves are sup-- ported bv radial brackets or arms 24? which rad ate from a collar or hub Qland thishub is collared to the standard by bolts or set -shown in Fig. 7

screws. These radial brackets 24* are preferably flat on top and the shelving is secured to them by screws or bolts or in any suitable manner. Thus every shelf is'secured to a plurality of radial brackets and is supported by and secured to a central standard in an adjustable manner, the collar or hub being adjustable upon the standard 26 by means of the bolts or setscrews which secure it thereto.

The shelves 2t are provided with dentated rims 52-1 so constructed as to permit the vertical members 40 of the bookracks' 45 to be inserted into the indentations and secured upon the shelf 2% in an adjustable manner by thethumbscrew 45 and the nut 45 and the washer 45, the said vertical member 46 being threaded to receive said nut and screw.

45 represents a bookrack, a plurality of which are adjustably secured to the shelves 2-1 in a radial manner so as to form upright partitions of variable extent. These bookracks are preferably constructed of wires so as to form a frame with one upright next the rim of the shelf and parallel to the standard and the other next the standard and parallel thereto. The' frame of the bookrack may be constructed of a single wire looped to a plurality of rings encircling or surrounding the standard and is substan- 1 tially rectangular. These bookracks may be covered with wire net or braced with rods.

l6 arethevrings encircling the standard and ll? are the wire loops formed by the wire of the frame 45 in passing around the body of the rings.

47 are the book clips secured to the upright Mi of the rack 4.5. These clips are preferably of spring metal with recurved jaws. l-T They are secured to the vertical member 46 by a bolt 4-7 a washer li and a thumbscr ew 47 which constrict the sides of the clip so as to bind it to the vertical rod sill, the bow of the clip being saddled to the rod. By turning the thumbscrew the clip is adjusted along the rod so as to position the clip as desired.

The eccentric clamp 46 is attached to the rings 46 in any suitable manner and is provided with a handle which gives it leverage by means of a cam contacting with theside of the standard.

The standard 26 is preferably a perforated, metalpipe vertically disposed within the case 29 and is journaled in bearings equidistant from the walls of the case. Itextends above and below the division plates of the fumigating chamber 31 and is seated within a ball and socket bearing 17 as and it is provided with a circular keyway near the top where it connected with a pneumatic pump 97. which. may be of'anv desired style or cons'liruclion. said pump being seated on a collar shown in Fig. 1. Thus the pump is secured to the collar so as to exhaust the contents of the fumigating chamber 31. The collar 26 being fast with the division plate 2) and the standard 26 being perforated, forming a fine for said chamber 31, the gases and air liberated in said chamber pass through said perforations and into the pump 21 when the vent lt is closed and said pump in operation.

27 as shown is a cylinder pump with a valve so arranged as to exhaust the contents of the chamber 31 through the flue of the pipe-standard 26. The plunger of this pump is operated by a pitman 27 which is actuated by a crank-pin 33 and a crank 33 in the manner illustrated. The crank 33 is mounted on a horizontal shaft 9 in the chamber 35, as shown in Fig. 1, the shaft 9 being journaled near its extremities by the hanger bracket 9 and the upright bracket 27 and a bearing let into the wall of the case 29 and secured thereto. The upright bracket 27 is secured to the pumpbase and the shaft 9 is driven by means of a. pulley S which is mounted on said shaft without the walls of the case 29.

The hanger bracket 9 is fitted with a suitable bearing 9 for journaling the shaft 9 and it is attached to the division plate 32.

Bolted to the division plate 1O within the drum-base 10 there is a bridge-bracket with a horizontal span 15 A cup socket i 1T let into the center of this span.

1'1" is a washer countersunk in the center of the span 15. The diameter of the washer exceeds the diameter of the cup-socket but the diameter of its core is smaller than the diameter of the cup.

17 represents a plurality of steel balls of equal size and sufficient in number to form a proper bearing for the spherical butt of the plug 17 which is inserted in the lower end of the standard 20. Thus the standard 26 is rotatablv seated in a ball bearing.

13 is a beveled gear with hub 13' by means of which it is keyed to the standard 213. as shown in Fig. 7.

14 represents each of two vertical. bcv eled gears disposed upon a horizontal drive shaft 11. Fig. 1. These gears mesh with the gear 13 and are mounted on the axle-sleeves 14 which are j urnaled in the piers 15 of the bridge-bracket 15. These sleeve axles work loose upon the shaft 11 but are incapable of longitudinal motion. the shaft 11 being encircled bv grooves to receive studs threaded into perforations in said sleeves. Intermediate the piers 15 and serrated rims of the axle-s eeves 14" is a sliding double-clutch 11 arranged to me h alternately with the teeth in th rims of the sleevoaxlcs 11.. This clutch feathered to the shaft 11 and is girdled by a collar 11 which runs in a groove encircling the clutch. To this collar is attached a bolt 18 which plays in a slot inserted in the lower member 18 of the shift bar 18 the bolthead overlapping the slot. 18 is bolted to 18 which is pivoted and secured by a second bolt to the span of the bridge-bracket 15. 18 is the bolt securing 1S to 18 and 18 is the pivot-bolt or axis of the shift bar 18. Thus when the striker bar 12 hinged to the table or web of the gear 13 and projecting above and beyond its fim strikes the shift bar 18 as the gear revolves the sliding double-clutch 11 meshes alternately with the teeth in the rims of the sleeve-axles.

A stud 12 projecting from the striker bar 12 fits into an aperture or perforation in the table of the gear 13 when the striker is in commission. \V hen in commission the striker bar oscillates the standard 26 by reversing the gear 1.3 alternately as it strikes the shift bar 18. \Vhen out of commission a simple rotary motion is imparted to the standard 26.

19 is a bolt secured by locknuts to the shift bar at its top; the shift bar being perforated to receive it. This bolt is horizontal and projects clear of the bridge bracket. It is flattened at its end farthest from the shift-bar and perforated in order to suspend a bob or plummet 1f) which depends from a line 19 Thus when the striker bar 12 engages the shift bar 18 the plummet 19 swings to the gravital line and assists the shifting of the clutch 11 The shaft 11 is journaled in the bearings 11 which are made fast with the walls of the drum base. \Vithout the base this shaft mounts two pulleys D and \Yhen the shaft is belted to a motor within the drum T base a pulley D is mounted on it within the drum base as shown in dotted lines. The pulley is provided with a handle 5 and may be used as a crank-wheel when so desired. shaft is belted to a motor or engine without the case. 7 is a belt which connects the pulleys 5 and S. S is a loose or slack pullev on the shaft S). Thus the commission by the use. of a belt shifter without interfering with the operation of standard 26.

31 represents the rotary fans disposed on shafts journaled in bearings made fast with the walls of the case 2 and disposed in such manner that the fans are within the fumigating chamber positioned (apposite the. shelves and facing the standard while their motors 21 are secured to a shelf or brackets il -supported bv the outer walls of the ease These motors may be e ectric or spring motors or may luir laced bv pulleys or sprockets. The .'.e and l nd of motor is deemed ininiater. l. The shaft 21 of these fans extends without the case 29 and is This handle is removed when the pump is putour'o'f driven by motor, pulley or sprocket as desired. The fans 21 are designed to blow air or gases previously liberatediin the fumigating chamber 31 into the crevices between the leaves and boards of the book and between the leaves when the supply is out 01?. They are provided with suitable drumshaped guards or cages, 21, to the band of which are secured suitable shields 21*. These fans may be arranged and constructed in any suitable manner no claim being made for the style of fan, guard, shield or motor employed.

A plurality of'electric lights .13) are arranged within the fumigating chamber in any suitable manner.

16 is the vent in the division plate 29 to the fumigating chamber 31. It is opened .and closed by a sliding valve 16 which is operated by a feeding device 16*. This valve is fitted into a channeled casing 16 and is integral with a vertical member which is perforated to receive the threaded rod of the feeding device. This feeding device comprises a threaded rod 16 which is j ournaled in the bearing integral with the walls of the case 29 so as to prevent air-leakage.

35 is the compartment which chambers the pneumatic pump 27 and immediately above it is the de-odorizing and sterilizing tank 37. The tank 37 is arranged to contain liquid and chemicals in solution and is provided With a Water gage 37 which is, mounted without the case 29.

- 36 is a gooseneck pipe connecting the chambers 35 and 37. It terminates in a perforated plate or drum 36 and is provided with a valve 36 as shown in Fig. 1. The purpose of this construction is to discharge the gases and air laden with germs beneath a perforated plate or within a perforated drum or rose nozzle and force them to rise to the surface in tiny globules. This tank 37 may be separated from the case or integral with it and it may be lined with any suitable material.

38 is the vent pipe to the case 29 and the tank 37 and it is provided with a valve 38.

39 is the chemical supply tank superposed upon the apparatus and connecting withthe tank 37 by a pipe 35% which is preferably fitted with a suitable valve 39*. This tank is provided with a neck and cap 39, the cap being threaded to the neck.

C is a handhole to the tank 37 and C" is a handhole to the chamber 29 is t hegusessure gage connected with the fumigating chamber 31 by means of a pipe and "cook, 29 and 29 respectively.

The gage to the gas tank T3 is litted to the pipe 22 intermediate the valve 2 and the pages.

The object of the gage B is to determine the pressure of gas inthe tank B and the object of the gage 22 is to determine the pressure of the air in the tank A.

40 represents the door to the operating chamber 31 wherein the books are deposited upon the shelves for fumigation.

41 is a heavy, plate glass window in the door -10 to demonstrate to the operator the efiiciency of the machine.

42 is the piano hinge which swings the aloor 40 and secures it to the jamb of the oor.

i3 is the lever which looks the door 40 by rotating a bolt 43* against a plate 43". This plate is integral with the door and is so constructed that the bolt presses the door farther in as the bolt advances its contact tangular recesses like a safe door to come spond with the rabbets in the stop. These rabbeted edges of the door and the recesses in the stop and the jambs are covered with rubber, felt'or some pliant and elastic material to render the closure air-proof under pressure from the bolt and to prevent leakage of gas'from within the case. Inasmuch as no gas is liberated in the base drum it s door 10 need not be so constructed.

Suitable stufiing boxes or stufiing glands with grease cups are provided for the bear ings in the division plate 10 and the walls of the case 29.

The motors 21 may be inclosed in airtight metal boxes integral with the case 29 and supported by and made fast to the outer wall of said case.

An electric heater of any suitable make, style or design, 37, and preferably inclosed in a water-proof casing 37 is installedjfin the tank 37' for heating the liquid contents of the tank to the boiling point, thus when the gas is discharged at the bottom off this tank it is forced to rise to the surface of "5' the boiling water in small globules and pass with the escaping steam through the final vent pipe 38. This is an alternative method for sterilizing the escaping gas and air.

Another alternative 'method may be employedxfoffumigating the books within the chamber 31. This need not be an alternative operation for it may be employed with the rotary fans. which are designed to blow the gas after its discharge into the faces,

and leaves of the books and between the In order to effect economy of gas during operation the chamber 35 may be conn cted with the tank A by a pipe 35 and the valve A in the supply pipe and opening necting thetank the pressure of air the chamber 31 the valves 22 in the pipes con- A with the chamber 31 or gas in the tank A and is equalized. Therefore when the chamber 35 is connected with the tank A under these conditions a circulation of gas from the chamber 35 to the tank A and thence from the tank A through the pipes 22 and their nozzles 30 back again into the chamber 31 is produced, the pump 27 operating to produce such circulation of gas or air, for it exhausts the contents of the chamber 31 into the chamber 35 and makes the gas pressure i the chamber 35 or the tank A and this gas naturally seeks an outlet by the ordinary process of expansion through the pipe 35* into the tank 1 and thence through the pipes 22* and the nozzles 30 into the chamber 31 where there is a comparative vacuum or a chamber whose air density is considerably interior to that in the chamber In this manner We may circulate the gas and produce constant discharge of gas through the 210i? zles 30 onto the faces, edges and b o the pages of the hooks positioned upright on the shelves 24: and secured to the hot or racks 45. As it will be necessary to 1 pose the germs in the books to the cites the germicidal gases for a period of before they can be destroyed and as i be necessary to keep the vol that all portions of every vol continuously exposed to gas during this period the value of this alternative method becomes apparent. Still it is not necessary to discontinue the use of the rotary tans while this alternative method is being employed. While this method is alternative it must be in eilect supplementary to the discharge of the gases from the tanks A and B into the chambe f-ll tor until a requisite quantity of gas from these tank" is introduced into the chamber a c Wire method of circulating ml the such gas car ot be employed.

l fhen electrical energy is employed for operating the apparatus, a switch or rheostat ll secured to the outer Wall of the casing as shown in Fig. 2. This switch or greater than that in either the chamber 31 rheost-at may be of any desired type or manufacture.
